Technical information

The low limit temperature alarm setpoint is the setpoint that
protects the chiller from undershooting past the required
process water temperature. The range for this setting is 19.4-
79 and the default is 39. For most applications this value will
need set about 3°F below the LTS value.

point temperature. The display returns to the actual

This feature will indicate when the chilled water system tem-
perature is above an acceptable level. This alarm will be indi-
cated by a flashing HtA. This is not a shutdown alarm only a
